EPC survey

An EPC survey report (Energy Performance Certificate survey) is the survey that takes place in order to produce a domestic or commercial property’s Energy Performance Certificate (EPC). This takes the form of a visit from an energy assessor who examines all sorts of variables to be able to accurately assess the energy performance of your property. The assessor will be both qualified and approved/accredited as required by law.

The type of thing that an EPC For You assessor looks at includes the heating system, the lighting system, how energy is kept in the property, the construction of the property itself, and its size. Features such as loft insulation, water heaters including hot water tanks and domestic boilers, radiators, and windows are all items that will need to be assessed when producing an accurate survey.

Unlike a building survey, which may involve invasive procedures, the EPC survey report is based entirely on observation. The time taken for an EPC survey depends on the type, size, and function of a property, but EPC For You will be able to give you an estimate once an appointment is booked.

To book an appointment you can choose your nearest office. Our locations include EPC Certificate LondonEPC Certificate Leeds and EPC Certificate Glasgow. For more office locations click here.

What’s Involved in an EPC Survey?

A friendly and professional energy assessor will visit to conduct the assessment and he/she will need access to every room in the property. Lighting is important in producing an accurate assessment and the number and type of fixed lighting will be considered. Any handbooks for a particular model of boiler for the property may also be helpful to the energy assessor when he/she comes to assess the heating system, although it is not essential. The energy assessor will observe and record any room thermostats and thermostatic radiator valves fitted as well as any other form of heating that may not be part of a central heating system, for example, in domestic properties particularly this could include open fires.

To be sure of accuracy, an energy assessor may take photographs of various parts of the property as well as outside the property – this will help them particularly if they need to override certain assumptions in relation to insulation values that the property may benefit from, despite it not being the norm for that type of property. Finally, the assessor will take measurements of the dimensions of the property and note any extensions or alterations.


After their visit, the EPC For You energy assessor places all of their observations of the property into a government-approved software program in order to perform an energy efficiency calculation. The program gives a value for the energy efficiency rating as well as another recommended value which represents the potential improvement that could be made to the property for energy conservation purposes. Based on this information, the EPC survey report will show how good or bad your property’s energy efficiency is. It rates your property’s energy efficiency from A to G, with A as ‘Very Efficient’ and G as ‘Very Inefficient’. The EPC is valid for 10 years and will be unique to the property address. If you need further advice on it, EPC For You can talk you through the scores and recommendations.
